LOCK.

SPECIFICATION forming part of Letters Patent No. 271,271, dated January30, 1883.

Application filed August 14, 1882.

To all whom it may concern Be it known that I, LYMAN RHOADEs,a citizenof the United States, residing in the city, county,and Stateot' NewYork,'have invented a new and useful Lock,of which the following is aspecification.

My invention relates to an improvement in locks and bolts; and theobjects ofmy improvements are to provide means for bolting a lock or a,series of locks instantaneously from any distance by means ofelectricity or by pulling a wire, and also to so construct the looksthat when locked, as aforesaid, the side plates of thelock will besecurely fastenedtogether upon the inside.

Figure l is a vertical view of the interior of the lock-case with theface removed, and sh owing the lock unbolted and the bolting devicesconnected with an electro magnet. Fig. 2 is a similar view with the faceof the lock removed, but with the lock bolted and with a string or wireattached to the locking-lever, hereinafter described, in lieu of theelectroinagnet. Fig. 3 is a view of an escutcheon, which is hereinafterdescribed and its uses set forth. Fig. 4 is a side view of the devicehereinafter described for fastening together the faces of the lock-case.

Similarletters refer to similar parts throughout the several views. t

A is a lever which works on a pivot, l. a is a pin which limits themotion of the lever. The end of the short arm of the lever A terminatesin the armature of an electro-maguet, 0, Fig. 1; or it may have a stringor wire, S, Fig. 2, or its equivalent, attached to it and operatedmechanically.

B is a plate,.with a hook-shaped projection, d, turning on a pivot onthe back face of the lock-case, and having a weight, It, attached to it,so arranged that the plate B fails when not held up by the lever A,resting in the notch i, as shown in Fig. 1. In the case ofavery heavybolt being used a spring may be attached to the plate B. I prefer not touse a spring, as without it very little power is necessary to free theplate B.

jand g are pins for raising'the plate B,f being moved by a key enteringat the key-kole n, and the pin g being on the plate B. Any

(No model.)

lock may be employed for throwing the bolt. The drawings represent aYale lock.

00 is the bolt of the lock. 6 is a pin attached to it and working in aslot in the lower end of the plate B, and so arranged that the bolt ismoved forward and backward by means of the falling and raising of theplate B. The bolt 09 terminates at its inner end in a point, x, whichpushes into the notch (l of the plate B when there is any pressureagainst the bolt; but when there is no pressure the bolt 00 hassufficient play for d topass when raised by a key.

The device for locking together the faces or plates of the case of thelook upon the inside are as follows: \Vhen the lock-plate B falls itpasses through eyes projecting from the'face of the front plate; or itmay pass through eyes projectingfrom both the front and back plates,thus securely locking them together. If the eyes project only from thefront plate, I prefer to have them pass through aperturesina rigid bar,K, fastened in the body of the look, so that the strain will come uponthe bar K, instead of upon the hook-plate B, in case an attempt is madeto pry off the front of the lockcase, and I prefer to have a pin,j,fastened to the hook-plate B to perform this operation of locking.

In the drawings, Figs. 1, 2, and 4, the eyes upon the front plate, L,are represented by 3 and t, and the apertures in the bar K arerepresented by r and s, and the hook j is shown in Figs. 2 and 4 passingthrough them.

On the outer surface of the jainb of the door when the lock is placedbehind the jamb, or on the edge of the door when the lock is on thedoor, is an escutcheon, D, perforated for the passage of the bolt, andfastened by the pivot 2, Fig. 3,in front of the outer end of the bolt00, so that when hanging free itcovers the end of the bolt. When thedooris open at the time that the plate B is released from the lever byelectricity or by pulling the wire the hook-plate only falls a shortdistance, as it is held back by the bolt coming in contact with theescutcheon D; but when the door closes and pushes the escutcheon asidesufficiently to allow the bolt to pass, the plate B will then fall andthe bolt be thrown forward into the 100 mature I), Fig. 1, or by meansof a cord or wire attached to the lever, as in Fig. 2. Thus the plate Bis released and falls by the force of gravity, or by a spring, and thebolt is moved forward by the pin e, and if the door, window, or draweris closed the bolt is thrown completely; but ifthe door, window, orother opening be not closed, then the plate B, although released fromthe lever A, falls only far enough to project the bolt against theescutcheon D, which holds it back until the door, by closing, pushes theescutcheon away from the bolt and allows it to be thrown into positionby the weigh ted plate B and pin a. When the lock is locked the bolt isprevented from being pushed back by the hook of the plate B, and at thesame time the front of the case is fastened to the body of the case bythe pin j entering into the two eyes that project from the front of thecase through the holes in the bar K. When an elect-ro-magnet and anarmature are used any number of locks connected by a wire may be lockedby a single circuit. When a cord or wire is used .the plate B may bereleased by a single mechanical operation, and cords or wires fromseveral locks may be connected to a single cord or its equivalent, sothat a single operation will release all the plates.

I do not confine myself to the form of upright bar K (shown) withapertures for eyes to pass through, as the bar may run horizontally; or,instead of a bar, asingle eye may project from the back of the case, sothat it will come between the two eyes on the front of the case and thepinj pass through the three eyes; or other similar device may be used.Nor do I limit my invention to the lever A, as a pin or springprojecting into the notch i may be used, the lever being used in thisspecification, as I believe it to be the simplest method for obtainingthe necessary result.

I know that gravity-latches have been long known, and also thatelectricity has been used for preventing the unlocking or retraction ofdoor-bolts, particularly in time-locks, by means of a dog or bolt.

What I claim as myinvention, and desire to secure by Letters Patent,isg 1. In a lock, the lever A, holding up the pivoted plate B when incontact with it, in com bination with the said pivoted plate B, weightedto fall by its own gravity when not in contact with said lever A, andalso in combination with the bolt 00, which is thrown forward andbackward by the falling and raising of the plate B, substantially as-andfor the purposes described.

2. The combination of the bolt 00, terminating in a point,0c,theweighted plate B, hooked and notched at (Z to receive the point an, andwith the notch 01 to receive the lever A, and the lever A fitting thenotch i, substantially as and for the purposes described.

3. The combination of the bolt 00, weighted plate B, and the lever A,one end of which is attached to an armature, b, of an elect-ro-inagnet,and an electro-magnet, G, substantially as and for the purposesdescribed.

4. The combination of the bolt 00 with the swinging escutcheon D,pierced at q, substantiallyas and for the purposes described.

5. The combination of. the hooked plate 13, the pin j, the bar K,pierced at 1" and s, with the eyes 3 and f, substantially as and for thepurposes described.
